> Project: Apache Trafodion
> Issue Type: Bug
> Components: sql-cmp
> Reporter: Qifan Chen
>
> It is found that the threshold to favor internal sort in memory may be set
> too high to favor sorting via SQL. In some test case, sorting via SQL on
> column took 2.5 minutes while the same task can be completed under 1 second.
